The SV-XPNDR-261 is a Class 1 transponder that can be used above those limitations. For US aircraft, the FAA 2020 ADS-B Out mandate requires a Class 1 transponder, so for US aircraft, the SV-XPNDR-261 should be installed.

Additional US ADS-B OUT Compliance Information: The FAA ADS-B "final rule" only allows the higher power Class 1 transponder to be used as an ADS-B Out transmit device for ADS-B Out mandate compliance on or after 2020. Therefore, for US customers, we recommend only the Class 1 SV-XPNDR-261.

Dynon Warranty, Support, and Service: These transponders come with a 3-year Dynon Warranty.

Mounting: At only 1 pound and 5.6" by 1.8" by 2.4", the transponder module can fit into the tiniest places and aircraft. A quick release mounting system allows for simple installation and easy removal if needed for service.
